UV Flashlight UVPRO
Don't forget the "UV" when selecting your next UV light.
Ultra Violet (UV) dye additives are specially formulated to fluoresce
in the presence of UV light rays. Hence the common industry names for
the two major components used with this technology, "UV" dye and "UV"
lights. Referring to the light spectrum chart below you can see that
true "UV" light is invisible to the human eye, with the closest visible
light colors being purple and blue respectively. The overall intensity
of UV light diminishes as you move from the invisible UV light range to
purple, then to blue and so on down the chart. Take care not to confuse
a lamp that emits high intensity visible blue light as superior to a
lamp tuned more efficiently to emit true UV light.
Why BLUE is NOT Necessarily Cool?
A correctly tuned Ultra Violet (UV) lamp should predominantly emit
invisible UV light waves with only a trace of visible "purple" or
"blue" light. The small amount of visible light is required to direct
the user's eyes to the leak search area, while the invisible UV light
rays actually illuminate the leaking dye. Lamps that emit large amounts
of visible blue light have been marketed heavily as being more powerful
and more effective at fluorescing leaks, backed by the obvious high
output of visible light. Knowing that UV dye additives requires
invisible true UV light rays to effectively fluoresce dispels this
claim altogether. In fact, special "blue blocking" glasses are required
for use with these high output blue lamps in order to remove the
nuisance blue light from the vision of the user during the leak search
process. Otherwise, the high output of light will mask the actual leak
or illuminating dye additive.
